'Property name with value in ICS file to set Out of Office event type in Google calendar

Can you please give me an advice, what is the correct property name with value (if there any is) for .ics file to display Out of Office status/event type in Google calendar ? Based on Google calendar API here, there is just attribute "eventType" with values and it does not work.

This is .ics file example with "eventType" attribute in:
